Because during the sedimentation of the flood plain - estuary fades, the conditions of sea level rising, tidal regime, sediment supply and accommodation space were suitable for the development of a tidal ridge system, the sand lenses associated with this facies may represent tidal ridge formation in the incised valley
在河漫灘河口灣相沉積期問，由於海平面上升、潮流體系、沉積物供給和可容空間條件適合一個潮流沙脊體系的發育，其中的砂質透鏡體可能代表了下切河谷內發育的潮流沙脊。Then it makes a summary of the terrestrial carbon deposition and points out several potential land - origin carbon traces including dam capture, deposition happening in floodplain, estuary and near - shore area, and terrestrial carbon precipitation
之後對陸地碳沉積機制進行了歸納，指出了包括大壩截留，河漫灘、河口近岸帶沉積及陸地碳沉降等幾種可能的陸源碳蹤跡。Those within existing stream channels are much less stable than overbank deposits.
現在河槽內沉積物的穩定性比河漫灘上沉積物差的多。The comparison of the component particles of baijiaziu profile and mafangtan profile with that of modern flood plain substance of weihe river indicates that the river impetus of weihe river has gradually been getting weaker, which reveals that it has gradually been getting dryer since the last 1300 years
西安高陵白家嘴河流沉積物粒度隨深度的變化及其與渭河現代河漫灘沉積物粒度特徵的對比表明，渭河近1 3ha來有流量減少，流速減慢，水深變淺的發展趨勢。At the end of late pleitocene, influenced by the climate of glacier period, the last great event of the region in the geological time was taken place so that the migration and extinction of organism species were resulted, loess accumulation was generally developed throughout the whole region, in the holocene, the most important environmental change was fluvial process, which was still influnced by two factors - neotectonics and palaeoclimatic changes
更新世晚期末，受末次冰期氣侯的影響，本區發生了地史時期的最後一次大事件，造成了物種遷移和絕滅，全區廣泛發育黃土堆積。進入全新世，本區環境變化以河流作用最為顯著，沉積物主要分佈在各大水系的河谷中，構成一、二級階地和近代河床與河漫灘堆積。The sediments of the incised valleys show an upward - fining succession, and can be grouped into four sedimentary fades : gravel lag - deposit of in - channel to partly over bank sediments of a meandering river, flood plain - estuary, estuary - shallow marine, and estuary sand bar, based on lithology, paleontology, and sedimentary textures and structures
根據巖石學、沉積結構和沉積構造特徵，本區下切河谷充填沉積物具有向上變細的沉積層序，可以劃分為4個沉積相類型：河床滯留沉積物到部分曲流河沉積體系的邊灘沉積、河漫灘河口灣沉積、河口灣淺海沉積和河口灣砂壩沉積。The seawater thereafter withdrawed southward away from the area, and form abundant stream, lake and delta deposit in shanxi stage and the early shihezi stage and stream, lake and bog deposit in the late shihezi stage and shiqianfeng stage
隨后，海水向南退出本區，並在山西期、石盒子早期形成廣泛的河流、湖泊和三角洲沉積，在石盒子晚期和石千峰期形成河流、湖泊和漫灘沼澤沉積。The researches of dynamic behavior and liquefaction potential of saturated sands have been further. however, more and more macroscopic liquefaction phenomena and experimental investigations show that different depositional environments lead to different structure of soils, while the influence of structure property of soils on liquefaction resistance is no less than that of density and consolidation stress and so on. ancient alluvial flat deposits, namely recently deposited soils, are easier liquefaction during earthquake
對於一般飽和砂土的動力特性和液化勢的研究已比較深入，然而，愈益增多的宏觀現象和試驗研究表明，由於土的沉積環境不同而導致土的結構性的差異，而土的結構性對抗液化能力的影響並不亞於密度、固結壓力等因素，古河漫灘堆積物即新近沉積土在地震當中更容易液化。Alluvial soil a type of soil formed on river floodplains and deltas, where new sediment is deposited on the land during floods
